Flexible granular pavements protected by sprayed seal surfacings are the backbone of the Australian and New Zealand road networks. Road agencies in .. Read more Australia and New Zealand have therefore been focused on producing quality, long-lasting sprayed seal surfacings. Such efforts include conducting research into bituminous binders as a key component of sprayed seals. A landmark achievement in this area was the Austroads sprayed seal trial sites at Coober Pedy in South Australia and Cooma in New South Wales. This webinar will present the outcomes of the Austroads research project which was conducted to monitor the performance of the trial sites up to about 8 years since construction. The project work includes comprehensive studies on the ageing properties of trial binders and their effects on the life of sprayed seal surfacings. He is currently the Chair of the Austroads - Bituminous Surfacings Technology Group (BSTG) and is the Project Manager for this project.
